GrCovertTemplate

Home » GrCovertTemplate

The Fingerprint SDK library must have been previously initialized.
The template array must be already allocated. The recommended size is GR_MAX_SIZE_TEMPLATE bytes.

Prerequisites

The template array must be already allocated. The recommended size is GR_MAX_SIZE_TEMPLATE bytes.

Return

On success, GR_OK is returned.
On failure, the appropriate error code is returned.

Parameters

[in] oldTpt	The template to convert.
[out] newTpt	The converted template.
[in,out] newTptSize	[in]The maximum size in bytes of the byte array supplied. [out] The size in bytes of the converted template.
[in] context	Context in which the extraction will be performed.
[in] format	The template format to be used.

Declaration

C++

int __stdcall GrConvertTemplate(char* oldTpt, char* newTpt, int* newTptSize, int context, int format);

Delphi

function GrConvertTemplate(oldTpt: Pchar; newTpt: PChar; var newTptSize: Integer; context: Integer; format: Integer): Integer; stdcall;

Sample Code

C++

int result;
// set current buffer size for the extract template
_newTpt->_size = GR_MAX_SIZE_TEMPLATE;
result = GrConvertTemplate((char*)_oldTpt, (char*)_newTpt->_tpt, &_newTpt->_size, GR_DEFAULT_CONTEXT, GR_FORMAT_DEFAULT);

// if error, set template size to 0

if (result < 0){

	// Result < 0 => conversion problem

	_newTpt->_size = 0;

}

Delphi



Var

	ret: Integer;

Begin

	// set current buffer size for the extract template

	newTemplate.size := GR_MAX_SIZE_TEMPLATE;

	ret := GrConvertTemplate(oldTemplate.tpt, newTemplate.tpt, newTemplate.size, GR_DEFAULT_CONTEXT, GR_FORMAT_DEFAULT);

	// if error, set template size to 0

	// Result < 0 => conversion problem

	if (ret < 0 ) then

		newTemplate.size := 0;
